President Trump has signed a bill that reinstates mandatory drone registration in the US, reversing a court ruling from earlier this year that eliminated the requirement. Mandatory drone registration was first established in the U.S. in late 2015 by the FAA, but the requirement was reversed earlier this year by the U.S. Court of Appeals for the District of Columbia Circuit after it ruled that the FAA lacked authority over such devices.

The reinstatement was included in the National Defense Authorization Act; although whether or not Trump was aware of its inclusion when he signed the bill into law is unclear.
